The Multilingual Children’s Association is a site that hopes to aid parents in the challenges of raising a multilingual child or children. You will find tips, tools, and resources for multilingual language learning. There is also a forum where you can ask questions to other multilingual parents (Do however note that the forum user activity is low). There is a frequently asked questions section on this website that provides good answers to many questions parents might have. While the site is quite old with some broken links, there is still useful information to be found here.
